I tend to push all of this work down to the database level. However, I can run into memory problems if I'm just selecting out (so you need to do a table read). The greater question is...with RapidMiner, is it better practice to deal with a database read directly into RapidMiner, or...a database read into a flat file, that is then read into RapidMiner...which is more efficient, and which is "good form".
